I need the answer quickly Example 5: A rear engine automobile is travelling along a track of 100 m mean radius. Each of the four roadwheels has a moment of inertia of 2.5 kg-m² and an effective diameter of 0.6 m. The rotating parts of the enginehave a moment of inertia of 1.2 kg-m?. The engine axis is parallel to the rear axle and the crankshaft rotates inthe same sense as the road wheels. The ratio of engine speed to back axle speed is 3:1. The automobile has a massof 1.6 tons and has its center of gravity 0.5 m above road level. The width of the track of the velhicle is 1.5 m.Determine the limiting speed of the vehicle around the curve for all four wheels to maintain contact with the roadsurface. Assume that the road surface is not cambered al and center of gravity of the automobile lies centrallywith respect to the four wheels.

A solid disc with radius R is connected to spring at point (d) distance above the center of disc. The other end of the spring is fixed to the vertical wall. The disc is free to roll without slipping on the ground. The mass of disc is (M) and the spring constant is (K). The polar moment of inertia for disc about its center is J = 1/2MR2 , so the natural frequancy for the system is 1 2K(R+d)² MR2 the Answer is O 1 2K 2п 3M
